it was announced in 2019 I think but game freak suddenly stopped talking about it and everyone assumed it had been cancelled until the last pokemon direct where they reannounced it i thinki thought pokemon sleep was just something they were meming about like that old tumblr post
didnt realize it actually was something that got announced and god it sounds terrifying
it's honestly very cool how pokémon has been using its mobile spin offs to promote some important routine stuff to their audience??
Pokémon Smile promoting oral hygiene, Pokémon GO promoting going outside for walks/ socializing, and now Pokémon Sleep seemingly going to promote healthier sleep schedules
